The following describes the method and device for preventing intrusion of a lateral turnout of a train provided by the embodiments of the present invention with reference to FIGS. 1 to 7 .

Fig. 1 is a schematic flow chart of a method for preventing intrusion of a train lateral turnout provided by the present invention, as shown in Fig. 1, including but not limited to the following steps:

Step 101 : acquiring the approach state of the target train, and acquiring the intrusion state of the preceding vehicle located in the intrusion area of the lateral switch;

Step 102: Formulate an intrusion protection strategy according to the approach state of the target train and the intrusion state of the preceding vehicle.

in,

It should be noted that the external facilities that cause the intrusion of the target vehicle can be mobile facilities, fixed facilities and foreign objects, and also include the preceding vehicle located in the intrusion area of the lateral switch. The present invention is only described as an example of the intrusion of the preceding vehicle on the running of the target train, which is not regarded as a specific limitation on the protection scope of the present invention.

Among them, the encroachment area refers to the area between the position of the section where the encroachment insulating section is located on the lateral turnout and the starting signal of the track.

The mobile blocking system has the function of vehicle-ground communication, and the method for preventing the intrusion of the train lateral switch provided by the present invention can be realized by establishing on the existing mobile blocking system.

First, the Radio Block Center (RBC) in the mobile blocking system can determine the approach status of the target train through the received relationship between the head position of the target train and the position of the incoming signal.

Secondly, RBC can also determine the intrusion state of the preceding vehicle according to the relationship between the rear position of the preceding vehicle located in the encroachment area of the lateral switch and the approach end signal on the turnout where the preceding vehicle is located.

Finally, according to the determined entry state of the target train and the intrusion limit state of the preceding vehicle, combined with the current running speed and load condition of the target train, an intrusion protection strategy that can ensure the safety of the target train can be comprehensively formulated.

Among them, if there are multiple lateral turnouts, it is necessary to determine the possible intrusion limit of each turnout, and determine the one that poses the greatest intrusion threat to the running safety of the target train as the target intrusion limit.

The method for preventing the intrusion of the train lateral turnout provided by the present invention is to correspondingly protect the intrusion of the train on the adjacent lateral track when the target train runs in the turnout section, mainly using the track circuit and the interlocked track occupancy inspection, The logic of the position report calculation of the on-board system, according to the operating characteristics of the freight train in different situations, controls the movement authorization during the train operation in real time, effectively ensuring that there is no lateral or directional switch on the adjacent track section of the line in front of the train operation. The intrusion of other trains improves the running safety of the train.

It should be pointed out that the entry status of the above-mentioned target train mainly includes the entry and non-entry, and the encroachment status of the preceding train mainly includes the encroaching and non-encroaching; in the case that the preceding train is a non-communication train In the case where the preceding vehicle is a communication train, the encroachment state is determined according to the protective envelope of the preceding vehicle.

The path state of the target train can be determined according to whether the head of the train has passed the path signal set in the corresponding path of the intrusion protection section. If the head of the train passes over the approach signal, the approach status of the target train is considered to have entered; if the head of the train does not pass over the approach signal, the approach status of the target train is considered to be no approach.

In the current rail transit, the running trains are mainly communication trains, but there are still many non-communication trains on the freight railway. The position of the rear of the vehicle, that is, whether the position between the wheelset and the coupler is beyond the lateral switch where it is located, and is located in the lane departure signal of the intrusion protection section, to determine the intrusion state of the preceding vehicle. If the position of the rear of the vehicle crosses the starting signal of the stock lane, it is considered that the intrusion status of the preceding vehicle is already infringing; Infringement.

Correspondingly, when it is determined that the preceding vehicle is a communication train, the protection envelope of the preceding vehicle can be determined according to the current state and position information of the preceding vehicle, so as to determine whether the protection envelope has crossed the above-mentioned lane departure signal. The intrusion status of the preceding vehicle. If the protective envelope crosses the starting signal of the stock lane, the intrusion status of the preceding vehicle is considered to have violated the limit; if the protective envelope does not cross the departure signal of the stock lane, the intrusion status of the preceding vehicle is considered to be unrestricted. Infringement.

The method for preventing the intrusion of the lateral turnout of the train provided by the present invention can distinguish the different situations that cause the intrusion to the main line operation of the train according to the positions of the front and rear cars and the different driving control modes, and formulate the following distinguishing measures. Corresponding intrusion prevention strategies provide the basis.

Based on the content of the foregoing embodiment, as an optional embodiment, formulating an intrusion protection strategy according to the approach state of the target train and the intrusion state of the preceding vehicle includes:

When it is determined that the entry status of the target train is not on the route, and there are other trains in the encroachment area of any lateral turnout, the established encroachment protection strategy is to authorize the movement of the target train ( Movement Authority, MA) is withdrawn to the approach signal.

Fig. 2 is one of the schematic diagrams of the driving scene in the encroachment area provided by the present invention. As shown in Fig. 2, in this scene, the head of the target train does not cross the incoming signal, but the preceding vehicle on the lateral switch S1 If the vehicle is in the intruded area and is in a parking state, the rear of the vehicle does not cross the lane departure signal of the turnout or its authorized envelope is located behind the lane departure signal, that is, the vehicle in front is in a non-intrusion state. Although the vehicle in front stops after entering the intrusion limit section, and the rear of the vehicle does not enter the path of the normal running target train, under normal circumstances, the target train will not collide with the vehicle in front, but it cannot be ruled out that the vehicle in front will retreat. There is still a risk of a collision between the two vehicles. At this time, the Radio Block Center (RBC) in the mobile blocking system will still withdraw the vehicle MA to the approach signal to prohibit the target train from entering the possible intrusion zone.

The method for preventing the intrusion of a train lateral turnout provided by the present invention, when it is determined that there is a preceding vehicle on the adjacent lateral track in the encroachment area, even if the preceding vehicle is in a stopped state and has not crossed the starting signal of the track where it is located , still considering the risk of accidental situations such as slippage, so that the MA of the target train located on the main line is withdrawn to ensure that the two cars will not collide to the greatest extent, and effectively ensure the driving safety.

Based on the content of the above embodiment, as an optional embodiment, the above-mentioned formulating an intrusion protection strategy according to the approach state of the target train and the intrusion state of the preceding vehicle may further include:

When it is determined that the approach status of the target train is already approached and the encroachment status of the preceding vehicle is not encroached, the encroachment protection strategy formulated is to cancel the movement authorization of the target train.

Fig. 3 is the second schematic diagram of the driving scene in the encroachment area provided by the present invention. As shown in Fig. 3, in this scenario, under the condition that the head of the target train has passed the approach signal, if it is determined that the intrusion limit There is a preceding vehicle in any lateral turnout in the protection area, even if the rear of the preceding vehicle does not cross the lane departure signal of the switch or its authorized envelope does not cross the lane departure signal, considering that the preceding vehicle may retreat In the case of a car slipping or slipping, the RBC in the mobile blocking system cancels the car MA in the present invention, so as to prohibit the target train from continuing to drive to the switch, thereby increasing the risk of collision with the preceding car.

The target train on the approach has passed the approach signal, but other trains appear in the intrusion protection area. At this time, the fixed blocking system cannot provide protection, and the intrusion of the train lateral switch provided by the present invention Restriction protection method, in the mobile blocking system, the RBC judges that it is currently in the intrusion protection area through the position information reported by the preceding vehicle, and there is a risk of intrusion, so the MA sent to the target vehicle is revoked, so that the target vehicle is no longer allowed to penetrate. possible intrusion zones. When necessary, it can also brake and stop in advance according to the current speed of the target vehicle.

Based on the content of the above embodiment, as an optional embodiment, the above-mentioned formulating an intrusion protection strategy according to the approach state of the target train and the intrusion state of the preceding vehicle may further include:

In the case where it is determined that the entry status of the target train is not entering the route, and the encroachment status of the preceding vehicle is already encroached, the established encroachment protection strategy is to withdraw the movement authorization of the target train to An approach signal, and output braking or remind the driver to slow down and stop through the train protection system of the target train.

Fig. 4 is the third schematic diagram of the driving scene in the encroachment area provided by the present invention. As shown in Fig. 4, in this scenario, under the condition that the head of the target train has not passed the approach signal, if it is determined that the intrusion limit There is a preceding vehicle in any lateral turnout in the protection area, and the rear of the preceding vehicle has passed the track departure signal of the turnout or its authorized envelope has passed the track departure signal, the present invention is implemented by the mobile blocking system. The RBC cancels the MA of the car to prohibit the target train from continuing to drive to the switch, and at the same time controls the output braking of its train braking system according to the current speed of the target train, or reminds the driver to slow down and stop, so as to avoid entering the restricted train track area as much as possible. section to prevent side collision of the target train.

In the protection method for train lateral turnout intrusion limit provided by the present invention, when it is determined that the rear of the preceding vehicle in the intrusion limit area has passed the departure signal of the track, the MA of the target train entering the road is withdrawn to The entry signal is used to prohibit the train from entering the intrusion area, which can effectively reduce the possibility of side collision between the target train and the preceding vehicle, thereby ensuring the safety of the train.

Based on the content of the foregoing embodiment, as an optional embodiment, the above-mentioned formulating an intrusion protection strategy according to the approach state of the target train and the intrusion state of the preceding vehicle may include:

When it is determined that the entry status of the target train is already entered, and the intrusion status of the preceding vehicle is intrusion, the established intrusion protection strategy is to cancel the movement authorization of the target train, And output emergency braking or remind the driver to stop emergency through the train protection system of the target train.

FIG. 5 is the fourth schematic diagram of the driving scene in the intrusion area provided by the present invention. As shown in FIG. 5 , in this scenario, in the case that the head of the target train has passed the approach signal, if it is further determined that the intrusion is In any lateral turnout in the limited protection area, the rear of the vehicle in front has also crossed the lane departure signal of the turnout or its authorized envelope has crossed the lane departure signal. In this scenario, it is very easy to happen. Two cars collided.

For this scenario, the present invention cancels the MA of the target train by the RBC in the mobile blocking system, and outputs 80kpa and above braking or emergency braking at the same time, so that the target train stops quickly and avoids entering the intrusion protection section.

The method for preventing the intrusion of the train lateral turnout provided by the present invention is to perform emergency braking on the target train when it is confirmed that the target train has entered the road and the intrusion state of the preceding vehicle is already intrusion, so as to ensure the maximum protection of the two trains. The occurrence of a collision accident.

Based on the content of the foregoing embodiment, as an optional embodiment, when it is determined that the obtained encroachment status of the preceding vehicle is infringed due to a fault in the track circuit, if the route of the target train is determined If the status is already on the road, the established intrusion protection strategy is to cancel the movement authorization of the target train, and output emergency braking or remind the driver to emergency stop through the train protection system of the target train.

If it is determined that the entry status of the target train is not entering the route, the established intrusion protection strategy is to withdraw the movement authorization of the target train to the approach signal and output it through the train protection system of the target train Brake or remind the driver to slow down and stop.

When it is determined that the intrusion section collected by the interlock is occupied by the preceding vehicle due to the fault of the track circuit, but there is no intruding train in each lateral turnout in the intrusion protection area, for the sake of prudence, The intrusion protection strategy provided by the present invention still adopts the retraction of the MA of the target train, and outputs emergency braking or reminds the driver to stop the emergency through the train protection system of the target train, so as to eliminate the reading of other signals caused by the fault of the track circuit. Take errors, thereby posing a threat to driving safety.

Wherein, in the case that the head of the target train has passed the approach signal, the above-mentioned withdrawing the MA of the target train means that the moving authorization of the target train will be cancelled; when the head of the target train has not crossed the approach signal In the case of , the above-mentioned withdrawing the MA of the target train refers to canceling the moving authorization of the target train and withdrawing the moving authorization of the target train to the approach signal.

The method for preventing the intrusion of the train lateral turnout provided by the present invention controls the MA in the train running in real time according to the track circuit and the interlocked track occupancy check, combined with the position report of the train within the range of the turnout from the on-board system. When the track circuit fails, corresponding braking measures can be taken according to the current running speed of the train, which effectively guarantees the running safety of each train.

Based on the content of the above embodiment, as an optional embodiment, if the distance between the intrusion-limited area and the starting signal of the track where the target train is located is greater than a preset distance threshold, the intrusion-limited area will be The protection strategy is finally formulated as follows: notify the ground personnel to clear the intrusion area.

As another optional embodiment, if the target train is a freight train and the running speed of the target train is less than a preset speed threshold, the intrusion protection strategy is finally formulated as: notifying ground personnel to The encroachment area is cleared.

In order to clearly illustrate the intrusion protection strategy in this scenario, the present invention further illustrates the following embodiments of the present invention in combination with freight railway operation and line data analysis:

1) For example, on the freight railway line, except for some stations, the rest of the intermediate stations are the main line passing stations under normal operation, and the running speed of the train within the range of two adjacent stations is generally above 70km/h, and the speed is reduced. Rarely.

2) When the driver enters the station via the side line to pick up or start the car, the speed is usually controlled within 20km/h, which is significantly lower than the normal running speed.

3) Since the freight train has the risk of coupler breakage and lane drop when emergency braking is implemented, especially when the speed is lower than 20km/h, the risk of emergency braking is even greater.

4) The mobile blocking system has the function of vehicle-ground communication, which can identify the scene within the range of the pick-up approach and the intrusion area in front of the front of the train after the train passes the approach signal for pick-up at the station.

5) There is a possibility that the intrusion-limited section is occupied when the train is picked up due to two situations of abnormal train slippage and fault occupation of the track section.

For freight railway operation and line data, the present invention provides different intrusion protection strategies according to different situations:

Scenario 1: When the target train passes through the main line of the station at 70km/h, the length of the pick-up throat area at the station where the intrusion-limited section is located is within the range of 274m-451m, which is less than the preset distance threshold.

According to the above-mentioned embodiment, when a 5,000-ton, 10,000-ton and 20,000-ton train enters the throat area at a speed of 70km/h, if the encroaching section is occupied by the preceding vehicle, the MA of the current train will withdraw, and the Trigger emergency braking.

However, in scenario 1, due to the high speed of the train and the short throat area, in the event of an intrusion, the driver has no additional means to protect it. Therefore, for the scenario in which the intrusion-limited section is close to the departure signal of the stock lane and the intrusion-limited section affects the main line operation of the train, the mobile blocking system will take the method of directly withdrawing the MA to let the train brake for protection.

Scenario 2: If the distance between the intrusion limit area and the departure signal of the track where the target train is located is far, and is greater than the preset distance threshold, when the main line of the target train passes, the station is arranged near the intrusion limit insulation section The probability of performing operations, such as shunting operations, is extremely small. The probability of a train parked on the track from abnormally slipping from the S1 and S2 strands to the section where the intrusion-limited insulation section is located is extremely small, and the probability is the probability of the occupation of the intrusion-limited section due to a fault in the track circuit.

For another example: for any intruded section at any station that affects the main line of the target train, the duty room and ground personnel will clear other lines that affect the main line of the train in advance, but the mobile blocking system will not prompt and inform the intrusion section. protection to avoid disturbance to the driver.

Scenario 3: When the freight train picks up and departs at the side line of the station, the train's running speed is generally below 20km/h. Since the freight train implements emergency braking when the speed is lower than 20km/h, the coupler breakage or the train derailment is more likely. Therefore, when picking up the car on the side line, under normal circumstances, other operations that affect the docking car will not be arranged near the intrusion-limited section where the car enters the road, and there are also cases where the track circuit in the intrusion-limited section is occupied by faults.

In Scenario 3, due to the low running speed of the train, the driver has the conditions to observe the line condition and perform the train braking operation under the condition of receiving and departing from the side line. For the intrusion scenario where the freight train line affects the receiving and dispatching of the side line of the mobile blocked train, the duty room and ground personnel shall clear other line operations that affect the pick-up and entry in advance, and the driver shall observe whether the intrusion occurs on the ground at low speed to carry out the train operation. At this time, the mobile blocking system will not prompt and protect the intruded section to avoid interference to the driver.

The method for preventing the intrusion of the train lateral turnout provided by the present invention, combined with the load and running speed of the target train itself, adjusts the intrusion protection strategy in a targeted manner, so as to ensure that the target train does not intrude with the preceding train method. On the basis of limiting accidents, if the ground personnel have enough time to clear the intrusion area, there is no need to adjust the driving state of the target vehicle, which makes the formulation and implementation of the strategy more scientific and reasonable.
